WARNING! This version is not compatible with older Arduino sketch. If you update the app you have to update the Arduino sketch also!
BlueCArd is a fully 3D printed open source indoor RC car. The brain of the card is an Arduino Nano compatible micro-controller and remote controlled through Bluetooth Low Energy (BLE).
My aim building this car was to make it very easy to build and as cheap as possible. That is why the car uses only standard elements and a mobile phone as a remote control.
The fine location permission is needed to search for Bluetooth devices. Without this permission the RC car can't be found!
The source code of this app and the Arduino sketch can be downloaded from github:
https://github.com/nenovmy/ardcar/
A detailed list of all needed elements can be found here:

And all 3D printable elements can be downloaded from thingiverse:

Build your own RC car today, have fun and write your experience in the comments!
